write the inequality in standard form for this situation: the CRHS science departmenr can spend no more than $2700 on textbooks this year. the department needs to buy both biology text books which cost $57 each and chemistry textbooks which costs $72 each

Question

A. 57x+72y>2700
B.57+72y<=2700
C.57x+72y<2700
D.57x+72y>=2700

Answer 1

Let x represent the number of biology textbooks and y represent the number of chemistry textbooks.

Since the biology textbooks cost $57 each and the department needs to buy x number of them, the cost of the biology textbooks is 57x.

Similarly, since the chemistry textbooks cost $72 each and the department needs to buy y number of them, the cost of the chemistry textbooks is 72y.

The total amount that the department can spend on textbooks is $2700.

Therefore, the inequality in standard form for this situation is:

57x + 72y ≤ 2700

So, the correct answer is B. 57x + 72y ≤ 2700
